PRINTING-MACHINE.

Specification of Letters Patent.

Patented 0ct. 16, 190s.

To all whom it may concern:

Be it known that I, HENRY A. WISE Woon, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Printing-Machines, of which the following is a specification.

The aim of this invention is to improve that class of printing-presses which are known in the art as traveling-cylinder printing-presses; and to this end the invention consists of the devices and arrangements described and claimed in this specification and illustrated in the accompanying six sheets of drawings, in which Figure 1 is a plan of the operating parts of a press constructed after my invention, the side frames being omitted. Fig. 2 is a longitudinal sectional elevation taken through the first impression-cylinder. Fig. 3 is a transverse section showing the driving-gear- .ing and the mounting of the reciprocating cylinders. Fig. 4 is a plan of the reciprocating slider. Figs. 5, 6, and 7 are details illustrating the way the antifriction-rolls for the impression-cylinders are mounted. Fig. 8 is a view similar to Fig. 2, the Web-tightening device being omitted. Fig. 9 is a view similar to Fig. 1, the web-tightening device, the intermediate looper, and the forwarding device being omitted. Fig. 10 is a sectional elevation similar to Fig. 2 of the device shown in Fig. 9, and Fig. 1 1 is a view showing the travel of the web when it is desired to perfect the web.

The improvements described and claimed in this case may be divided into six different heads, the first of which covers an arrangement. of printing mechanisms and turner devices whereby two independent webs can be printed or a single web can be perfected (printed on both sides) or twice printed upon the same side; second, in combination with the same of a peculiar intermediate forwarding-device; third, of a web-tightening device which puts a tension on the web during the printing operation and releases the web during the feeding-shifting operation; fourth, of a peculiar inking apparatus; fifth, in the peculiar mounting for the reciprocating impression cylinder or cylinders, and, sixth, in the peculiar driving mechanism for the reciprocating cylinder or cylinders.

' In this present invention I arrange two substantially similar printing mechanisms side by side and preferably in substantially the same horizontal plane. At the end of the press I provide a suitable turner or deflector device. By this arrangement two webs can be led through the press and printed on one side, or a single web can be led through one printing-machine and then deflected to the other printing-machine either to be perfected or to be again printed upon the same side.

Referring now to the first three sheets of drawings and in detail, it will be seen that A and B represent two reciprocating impression-cylinders which are arranged, preferably, end to end and are mounted in the respective carriers C, O, and O and by the driving mechanism hereinafter described the two impression-cylinders are reciprocated back and forth over two type-beds D and E, ar-

ranged side by side. This is the preferred arrangement, although, of course, so far as my invention is concerned, the two impressioncylinders could be moved separately, if desired. The impression-cylinder A has a gear a arranged at the end thereof, which meshes with a stationary rack a, and the impressioncylinder B has a similar gear 0, which meshes with a stationary rack c, and by this means the impression-cylinders will oscillate as they are reciprocated to correctly register with the forms in the usual manner. Par-ts of the gearing for driving the various parts are omitted, as the same are well understood and can be arranged by the ordinary printingpress mechanic. I have shown in the sheets of drawings under discussion the arrangement where a web is being twice printed upon the same side by the two printing mechanisms. With this arrangement I mount a single webroll W upon the shaft w at the left-hand end of the press. From the web-roll the web is led between the continuously-running feeding-in rollers 13, 1 1, and 15, then down under the looping-roller 24, which is mounted in arms 17, which are pulled normally down by the springs 18, which are connected to the arms 17 and stationary points 19. The ends of the arms 17 are yoked, as at 21, and these "yokes straddle a shaft 22 and carry rollers 20, which bear on the cams 23, mounted on the shaft 22. This shaft 22 is geared, preferably, to turn twice for each complete forward and backward reciprocation of the impressioncylinders, whereby the feed can take place when the impression-cylinders are off the forms in either direction.

From the looping-roller 24 the web passes over the roll 25, then under the web-tightener 27 which is mounted in arms 28, which are secured to the shaft 29. Connected to one of these arms 28 is a rod 30, which screws into a coupling 31 and which is held in place by check-nut 32. Also screwing into the coupling 31 is a rod 34, which is held in place in the coupling by a check-nut The lower end of this rod 34 is formed into a yoke 35, which straddles a shaft 38, and the yoke 35 carries rollers 36 and 37, which bear on the cam 39, secured to the shaft 38. This shaft 38 is driven at the same speed as the shaft 22, and the cam 39 is so proportioned that while the impression cylinders are printing the roller 27 will be kept down, but that while the feeding takes place the roller 27 will be slightly lifted. By the coupling before described the action of this tensioning device may be easily adjusted so that the proper pull or tension will be put on the web, the screw-threads of the shafts 30 and 34 being of opposite pitch, so that by turning the coupling 31 adjustment is obtained be,

tween the cam and the arms 28.

From the tightening-roller 27 the web passes up over the guiding-roller 300, then to the guide 40, carried by the reciprocating carriers, under the impression-cylinder A, then around the guide 41, also carriedby the reciprocating carriers, to the stationary guideroll 42, and then under anotherweb-tightener 43. This web-tightener 43 is arranged similarly to the web-tightener 27 and is mounted in arms 44, which are secured to the shaft 45. Connected to one of the arms 44 is a rod 46, which screws into the coupling 47 and is held in place therein by a check-nut 48. Also screwed into the coupling 47 is the rod 50, which is held in place by the checknut 49. The rod 50 is yoked, as at 51, and straddles the shaft 53. The yoke 51 carries the rollers 52 and 55, which bear against a cam 54, mounted on shaft 53, similar to cam 59. This cam 54 is timed to operate with the cam 39. Of course, so far as the scope of my invention is concerned, a single webtightening roll could be used, and when only a single roll is used it is preferred to use the roll 27, so as to draw the slack backward through the press. These tightening-rolls 27 and 43 may be also used to slightly adjust the register of the web. Suppose, for instance, it is desired to adjust the register a trifle to the rear, the sleeve nut or coupling 31 would then be tightened and the coupling 47 would be loosened. This will slightly change the action of the tightening-rollers and will adjust the register as desired with out effecting the operation of any of the other parts of the machine.

From the web-tightener 43 the web passes up over the guide 56, then down under the looping-roller 66, which is mounted in arms 59, which are normally pulled down by springs 60, secured to said arms and stationary points. These arms 59 have yokes 63, formed at the ends thereof, which straddle the shaft 65,,and also rollers 62, which bear on cams 64, secured on the shaft 65. The cams 64 are turned in unison with the cams 23, but are oppositely arranged on the shaft,

as shown, whereby the proper feeding action" can take place around the impression-cylinders, the looping-roller 66 moving up as the looping roller 24 moves down, and vice versa.

From the looping-roller 66 the web is led up over the roller 67, down under the register roll 68, which is mounted in arms 69, secured to the shaft 70, then up over the guidingroller 71. From this point the web, if desired, can be led out of the press by suitablyoperating forwarding mechanism, such as rollers 13, 14, and 15, and also, ifdesired, the two parts of the press can have webs led through them in this manner, whereby each impressioncylinder will print a web upon one side. In most cases, however, it is desired to perfect or to print the web again on the same side. able turners or deflectors, which will deflect the web backward parallel to its original pathway to the impression cylinder B. When it is desired to print the web again upon the same side, two oppositely-arranged turners or turner-surfaces, as 72 and 73, are used, as shown, the web passing up over the turner 72 and down over the turner 73. It will be seen also that as the web passes through this turner device that the first printed side of the same will not touch either turner-bar. If it is desired to perfect the web, the web from the turner 72 is led out to a parallel roller 75, down over the same, and up over a turner-bar 74, mounted parallel to the turner-bar 72. This path of the web is shown in Fig. 11 and will turn the web over. Also it will be seen that the web in passing through this turner will not have its first printed side brought in contact with any of the turner bars or rollers. In building the press I put all these turner-bars (shown in Fig. 1) in place, so that the web can be perfected or twice printed as desired, depending upon the way the same is led through the turner device.

When the web is deflected back, it is carried around substantially the same guidingrollers of the second press as of the first press, except that in some instances it is carried on opposite sides of the rolls. Thus from the turner the web is led over the guide-roll 71, and then under the guide-roll 67 then up over a looping-roller 58, which is mounted in the arms 59. Two looping-rollers 58 and 66 To do this, I provide suitare preferably arranged in the arms 59, so that the web in the second press can be led through the machine, if desired, as in the first press, for the purpose of printing on one side of two webs. By means of this looper arranged in the path of the web between the two impression-cylinders it will be seen that the web will run continuously around the turner device, which is advantageous in that considerable friction is generally created on a turner device, and this friction will not affect the feed if the web is run continuously around the turner device.

From the looping-roller 58 the web passes under a roll 57, then under the web-tensioner 43, then over the roller 42 to the guide 41 at theright of the impression-cylinder B, then under the impression-cylinder B, then up over the guide 40 at the left of the impression-cylinder B. From this guide 40 the web is led around the guide 300 under the web-tightener 27, then up over the guide 25, then under the roll 26, up over the roll 16, and then out through the continuously-running rollers 15, 14, and 13, as shown. In this passage the web is either perfected or twice printed on the same side as desired. This web-manipulating mechanism is preferably so arranged as to shift the web forward around the impression-cylinders when they are off impression in either direction. The term off impression is well known in the art to mean when not in printing contactthat is, the cylinders are off impression in either direction when they are moved out of printing contact with the forms placed upon the stationary beds.

Arranged at each side of each impressioncylinder are four form-rollers, as F, F F and F", at the left of the impression-cylinders and F F F and F at the right of the impressioncylinders. Two distributer-rollers for these two sets of form-rollers at each side of the impression-cylinder are also used, as the distributers G and G at the left of the impression-cylinders and the distributers G and G at the right of the impression-cylinders.

Arranged ateach end of each bed is an inking apparatus which consists of the drum cylinders 73 and 74, the form or carrying rollers 75 and 76, and the ink-drum 760. Ink is deposited upon the ink-drum 760 by means of the vibrating ductor-rolls 7 7, mounted on arms 78 on the shaft 79, from ink-fountains 80. The ink-drunrs 73 and 74 at the left of the beds are arranged to give ink to the two sets of form-rollers at the left of the impression-cylinders, and the ink-drums 73 and 74 at the right of the beds are arranged to supply ink to the two sets of form-rollers at the right of the impression-cylinders. By

this means a very complete and well-distributed supply of ink is given to the forms. By the mechanism before described I am enabled to rapidly run the press on different kinds of work as desired.

So far as parts of my invention are concerned the press may be considered as a single pressthat is, as using only the impression-cylinder A and the bed D.

As before stated, so far as the web-tightener is concerned only a single tightener may be used, if desired.

The driving mechanism for reciprocating the impression-cylinders and the mounting of the impression-cylinders is shown in the third sheet of the drawings. In this sheet 100 and 101 represent the side frames of the machine. 102 represents a strong bracket or brace which is secured between these side frames, and formed in this bracket is a bearing 103. Journaled in. the bracket 102 and in the side frame 100 is the driving-shaft 104, which carries a bevel-pinion 106 and to which power can be applied by any suitable means, as from the gear 105. The bevel-pinion 106 meshes with and engages a large bevel-gear 107, which is mounted on a shaft which is fitted or journaled in. the bearing 103. Arranged on the top of this bevel-gear 107 is a crank-pin 108, which carries a crank-block 109, which fits in the slot 110 of the reciprocating yoke or slider 111, which is arranged to slide parallel to the movement of the impression-cylinders on suitable guides or ways 120, formed on the side frames 100 and 101, as shown. This reciprocating yoke or slider carries two racks 112, as shown. These racks 112 mesh with gears or pinions 115, mounted on a shaft 113, which is journaled in the side frantes 100 and 101 and in brackets 114, depending from the beds. Mounted on this shaft 113 are two gears 116 and 1160, which are larger than the pinions 115, and these gears mesh, respectively, with the racks 117, secured to the bottoms of the carriers C and C Arranged on the middle of the shaft 113 between the bearings 114 is a gear 118, which meshes with a rack 1.19, secured to the bottom of the carrier C. By

this means the reciprocating motion of the yoke or slider 111 will be multiplied and transmitted to the reciprocating carriers to reciprocate the impression-cylinders. Also it will be seen that the shaft 113 and its two pinions meshing with the racks 112 acts as a squaring-shaft for the slider. By this means a very smooth, positive, and direct. movement will be imparted to the reciprocating impression-cylinders. Also it will be seen that the entire driving mechanism for the press is housed inside of the press between the side frames, which is an important point in practice, as the workman or operator cannot become entangled or be struck by the reciprocating or moving parts of the driving mechanism.

The carriers C and C are the same in construction and arrangement except that they IIO are rights and lefts. The middle carrier C is the same as the carrier C except that it is double. These carriers are peculiarly mounted, and a description of the mounting of one carrier will suffice for the three. I will describe the mounting of the carrier C This carrier O has a suitable groove C out therein, and below this groove is arranged a tongue C. Fitting into the groove C is a piece 121, which is secured to the top of the side frame 101, which piece 121 takes theupward strain due to the impression. Arranged on this piece 121 is a rack 122, and secured to the tongue C of the reciprocating carrier is a rack 123. Arranged between the tongue and the piece 121 are a series of antifriction pressure-rollers 124, which are mounted so as to be independently movable with respect to the carriers. It will thus be seen that these friction-rollers are interposed so that the upward pressure between the tongue C and the guide 121 will not create much friction.

These rollers 124 are mounted on studs 127,

secured to a thin metal strip 125, whereby they will all move in unison. Mounted on one of these rollers 124 is a pinion 126, which meshes with the racks 122 and 123. By this means as the carrier reciprocates forward and backward the antifriction pressurerollers will be moved at one-half the speed or distance of the carrier. This arrangement of antifriction pressure-rollers will allow for an easy and nice movement of the carriers and the upward pressure due to the impression will not create much friction be tween the parts. This mounting is important when it is desired to get high speed out of the device. The mounting of the middle or intermediate carrier C is the same as that of the carrier 0 except that the same is doubled or two pieces 121 are secured to the intermediate frames. It is not thought necessary to describe the mounting of this carrier (1 further at length, as the same is merely a double carrier, one-half of which is used practically for each impression-cylinder. The bearings in which this double carrier C is mounted project up from between the beds D and E, as shown.

If but one-half of the press is used, the proj ections would be, of course, in the side frames, and where I use the term frames on each side of the bed I mean, of course, to include the frames that would support a single bed at the sides thereof.

Any arrangement of frames or beds which will constitute guides or guideways for the carriage may be used. The web-tensioning device can be omitted, of course, if desired. In Fig. 8 I have shown this arrangement of press, which is substantially the same as that shown in Fig. 2 except that I have provided an additional roller 670 for forwarding the web through the turner device. In this arrangement the web after leaving the first impression-cylinder A is looped up over the looping-roller 58 and the looping-rollers 58 and 24 are operated in unison. After leaving the turner the web is looped under the looping-roller 66 and after leaving the im pression-cylinder B is looped up over the roller 16. I have connected the two loopers to be operated from the same cams 200. These cams 200 are mounted on a shaft 201, and straddling the shaft 201 are yokes 202, which carry rollers 203 and 204, which engage the cams 200. Connected to these yokes are rods 205 and 206, which connect by suitable bell-cranks 207 and 208 to the arms 17 and 59. As thus organized the press operates as before described except that the web-tensioning device is not used.

In some cases I also contemplate omitting the intermediate web-forwarding device for forwarding the web around the turners, and this arrangement is shown in Figs. 9 and 10, which arrangement is simply the same as before described, omitting the tensioning and intermediate forwarding devices. In this use of the machine of course the intermediate carriers for the cylinder could be omitted, if desired, and the two beds oper ated as upon one bed, and this arrangement I consider within the scope of my claims.

While I have shown in the drawings the two beds arranged in mathematically the same horizontal plane, it is evident, of course, that one bed could be higher or lower than the other or one bed in advance of the other, both of these arrangements coming within the scope of my invention, which is to arrange the beds substantially side by side.

As before stated, many of the improvements may be applied to a single machinethat is, to a machine in which but one impression-cylinder and bed are usedand so far as the scope of this part of my invention is concerned it may be considered that onehalf of my machine is used.

The details and arrangements of parts herein described may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.
